The overall survival (OS) according to pStage. A The OS in 239 patients with pStage I colorectal cancer. The OS rates have no significant difference between low SAS (≤6) and high SAS (≥7) (p =0.172). B The OS in 211 patients with pStage II colorectal cancer. The OS rates in the low-SAS group (≤6) were significantly lower than that in the high-SAS group (≥7) (p =0.048). C The OS in 188 patients with pStage III colorectal cancer. The OS rate in the low-SAS group (≤6) was significantly lower than that in the high-SAS group (≥7) (p =0.016)
